Absolutely. It is impossible to correctly self-diagnose one's own sleep apnea (sa). Usually it is the bed partner who complains about the robust snoring, gasping, choking, or cessation of breathing. The sleeper just sleeps through it. But sometimes, if the sa is bad enough, you can have an episode that does startle you awake. You are describing a sa event. See your md to get a sleep study and treatment.

Stopped breathing. Yes. Go to a sleep lab for testing.
